I'm diagnosed depression with psychotic features so I only hear voices & have delusions when depressed. I find that music can help drown out voices when they're becoming annoying/scary, which you might like to try. Also like keepingalice said, opening a dialogue with them might help e.g. "why are you being so mean?" I've found that since I understand where my voices are coming from (past experiences), they hold much less power over me and is probably the reason I've avoided hospitalisation.

Wishing you all the best,
